Answer:
Explanation:
import numpy as np
#we define the function that takes year1 and year2 array values and return the maximum of the difference.
def max_diff(year1, year2):
#we pass the difference along the array into diff
diff = np.diff(year1, year2)
#then we take the max value
max = np.argmax(diff)
return max
#the function can be called by initializing
max_val = max_diff(year1_array, year2_array)
